Skip to main content



Please note that in order to use these hooks you must be in a component (you can't use them directly from a callback function). Anyhow, callbacks usually include a FireCMSContext, which includes all the controllers.

You can use this controller to open the side entity view used to edit entities. This is the same controller the CMS uses when you click on an entity in a collection view.

Using this controller you can open a form in a side dialog, also if the path and entity schema are not included in the main navigation defined in FireCMS.


If you want to override the entity schema of some entity or path, at the app level, you can pass a SchemaResolver to your FireCMS instance to set an override.

The props provided by this context are:

  • close() Close the last panel
  • sidePanels List of side entity panels currently open
  • open (props: SideEntityPanelProps & Partial<SchemaSidePanelProps>) Open a new entity sideDialog. By default, the schema and configuration of the view is fetched from the collections you have specified in the navigation. At least you need to pass the path of the entity you would like to edit. You can set an entityId if you would like to edit and existing one (or a new one with that id). If you wish, you can also override the SchemaSidePanelProps (such as schema or subcollections) and choose to override the FireCMS level SchemaResolver.


import React from "react";
import { useSideEntityController } from "@camberi/firecms";
export function ExampleCMSView() {
const sideEntityController = useSideEntityController();
// You don't need to provide a schema if the collection path is mapped in
// the main navigation or you have set a `schemaResolver`
const customProductSchema = buildSchema({
name: "Product",
properties: {
name: {
title: "Name",
validation: { required: true },
dataType: "string"
return (
onClick={() =>{
entityId: "B003WT1622",
path: "/products",
schema: customProductSchema
Open entity with custom schema

Schema resolver#

You may want to override the schema definition for particular entities in. In that case you can define a schema resolver in the FireCMS level.

In order to do that, you can specify a SchemaResolver that is in charge of resolving the path and entityId and returning a SchemaConfig, where you can specify a custom schema (including callbacks and custom views), permissions and subcollections

import { buildSchema, SchemaResolver } from "@camberi/firecms";
const customSchemaResolver: SchemaResolver = ({
}: {
entityId?: string;
path: string;
}) => {
if (entityId === "B0017TNJWY" && path === "products") {
const customProductSchema = buildSchema({
name: "Custom product",
properties: {
name: {
title: "Name",
description: "This entity is using a schema overridden by a schema resolver",
validation: { required: true },
dataType: "string"
return {
schema: customProductSchema,
// permissions: ...,
// subcollections: ...,

Then you can pass schemaResolver to your FirebaseCMSApp or FireCMS
