sidebar_label: Collections

In FireCMS, collections represent groups of entities.

You can find collections at the top level of the navigation tree (the entries displayed in the home page and the navigation drawer), or as subcollections

The name and properties you define for your entity collection, will be used to generate the fields in the spreadsheet like collection tables, and the fields in the generated forms.

:::note FireCMS provides around 15 different fields (such as text fields, selects, and complex ones like reference or sortable array fields). If your use case is not covered by one of the provided fields, you can create your own custom field. :::

You can find collection views as the first level of navigation in the main menu, or as subcollections inside other collections.

  • name The plural name of the collection. E.g. 'Products'.

  • singularName The singular name of an entry in the collection. E.g. 'Product'.

  • path Relative Firestore path of this view to its parent. If this view is in the root the path, it is equal to the absolute one. This path also determines the URL in FireCMS.

  • properties Object defining the properties for the entity schema.

  • customId If this prop is not set, the ID of the document will be created by the datasource. You can set the value to 'true' to force the users to choose the ID. You can set the value to true to allow the users to choose the ID. You can also pass a set of values (as an EnumValues object) to allow users to pick from those only.

  • subcollections Following the Firestore document and collection schema, you can add subcollections to your entity in the same way you define the root collections.

  • defaultSize Default size of the rendered collection.

  • group Optional field used to group top level navigation entries under a navigation view. If you set this value in a subcollection, it has no effect.

  • description Optional description of this view. You can use Markdown.

  • filterCombinations If you need to filter/sort by multiple properties in this collection, you can define the supported filter combinations here. In the case of Firestore, you need to create special indexes in the console to support filtering/sorting by more than one property. You can then specify here the indexes created.

  • initialFilter Initial filters applied to this collection. Defaults to none. Filters applied with this prop can be changed by the user. e.g. initialFilter: { age: [ ">=", 18 ] }

  • forceFilter Force a filter in this view. If applied, the rest of the filters will be disabled. Filters applied with this prop cannot be changed. e.g. forceFilter: { age: [">=", 18] }

  • initialSort Default sort applied to this collection. It takes tuples in the shape ["property_name", "asc"] or ["property_name", "desc"]

  • Actions Builder for rendering additional components such as buttons in the collection toolbar. The builder takes an object with props entityCollection and selectedEntities if any are set by the end user.

  • pagination If enabled, content is loaded in batches. If false all entities in the collection are loaded. You can specify a number to specify the pagination size (50 by default) Defaults to true

  • additionalFields You can add additional fields to both the collection view, and the form view by implementing an additional field delegate.

  • textSearchEnabled Flag to indicate if a search bar should be displayed on top of the collection table. Please note that you need to add

  • permissions You can specify an object with boolean permissions with the shape {edit:boolean; create:boolean; delete:boolean} to indicate the actions the user can perform. You can also pass a PermissionsBuilder to customize the permissions based on user or entity.

  • inlineEditing Can the elements in this collection be edited inline in the collection view. If this flag is set to false but permissions.edit is true ,
    entities can still be edited in the side panel.

  • exportable Should the data in this collection view include an export button. You can also set an ExportConfig configuration object to customize the export and add additional values. Defaults to true

  • hideFromNavigation Should this collection be hidden from the main navigation panel, if it is at the root level, or in the entity side panel if it's a subcollection. It will still be accessible if you reach the specified path. You can also use this collection as a reference target.

Sample collection

:::tip You don't need to use buildCollection or buildProperty for building the configuration. They are identity functions that will help you detect type and configuration errors :::

import {

            name: "Price",
            validation: {
                requiredMessage: "You must set a price between 0 and 1000",

            dataType: "array",
            name: "Related products",
            description: "Reference to self",
            of: {
                dataType: "reference",

                    name: "External id",
                    dataType: "string"
    // additionalFields: [productAdditionalField], // Example below
    filterCombinations: [{ price: "desc", available: "desc" }],
    permissions: ({ user, authController }) => ({
        edit: true,
        create: true,
        delete: false

Additional columns

If you would like to include a column that does not map directly to a property, you can use the additionalFields field, providing a AdditionalFieldDelegate, which includes an id, a title, and a builder that receives the corresponding entity.

In the builder you can return any React Component.

:::important If your additional field depends on the value of another property of the entity you can define the dependencies prop as an array of property keys so that the data is always updated. This will trigger a rerender whenever there is a change in any of the specified property values. :::


import {
} from "@camberi/firecms";

type User = { name: string }

export const fullNameAdditionalField: AdditionalFieldDelegate<User> = {
    id: "full_name",
    name: "Full Name",
    builder: ({ entity }) => {
        let values = entity.values;
        return typeof === "string" ? : "No name provided";
    dependencies: ["name"]

const usersCollection = buildCollection<User>({
    path: "users",
    name: "User",
    properties: {
        name: { dataType: "string", name: "Name" }
    additionalFields: [

Advanced example

import {
} from "@camberi/firecms";

export const productAdditionalField: AdditionalFieldDelegate<Product> = {
    id: "spanish_title",
    title: "Spanish title",
    builder: ({ entity, context }) =>
        <AsyncPreviewComponent builder={
                path: entity.path,
                collection: localeSchema
            }).then((entity) =>

:::tip AsyncPreviewComponent is a utility component provided by FireCMS that allows you to render the result of an async computation (such as fetching data from a subcollection, like in this case). It will display a skeleton loading indicator in the meantime. :::


Subcollections are collections of entities that are found under another entity. For example, you can have a collection named "translations" under the entity "Article". You just need to use the same format as for defining your collection using the field subcollections.

Subcollections are easily accessible from the side view while editing an entity.


:::tip If you need to have some filters and sorting applied by default you can use the initialFilter and initialSort prop. You can also force a filter combination to be always applied by using the forceFilter prop. :::

Filtering is enabled by default for string, numbers, booleans, timestamps and arrays. A dropdown is included in every column of the collection where applicable.

Since Firestore has limited querying capabilities, each time to apply a filter or new sort, the previous sort/filter combination gets reset by default (unless filtering, sorting by the same property).

If you need to enable filtering/sorting by more than one property at a time, you can specify the filters that you have enabled in your Firestore configuration. In order to do so, just pass the indexes configuration to your collection:

import { buildCollection } from "@camberi/firecms";

const productsCollection = buildCollection<Product>({
    path: "products",
    name: "Product",
    properties: {
        // ...
    indexes: [
            price: "asc",
            available: "desc"
