Overview
This guide will help you to implement a custom form layout for your Headless CMS content models. By default, our Headless CMS allows you to organize content model fields in a grid layout. That is fine for a basic UI, with several fields. However, as your content model grows, you may need to organize the UI to be more visually appealing and easier to navigate for your content editors.
Custom form layouts will also come in handy if you need to show or hide certain elements of the form based on content editor’s permissions, or even render additional UI like helper text, links, images, etc.
Plugin Type
There’s only one plugin you need to implement to create a custom form layout: CmsContentFormRendererPlugin.
Plugins of this type require a modelId
(to match the model in your Headless CMS), and a render
function which returns a React element which will be rendered instead of the default grid based layout.
Simple Layout
The plugin demonstrated above renders a content form for pizza
content model. fields
object contains key-value pairs of content model fields, with key being the fieldId
(defined in the content model editor), and value being a React element rendered using the appropriate field renderer. All you need to do is place those field elements in your new layout.
Conditional UI
If you want to render UI based on user’s permissions, you’ll need to use security hook. In this example, we’re creating a more elaborate layout for our form, using the Tabs
component:
Here’s what a default layout looks like:
Once we import the plugin and register it in our admin
app, we get our custom layout:
You can see the Recipe
tab is hidden. That’s because we don’t have the necessary permission to view it.
Custom UI Elements
Using form data you can also render other UI elements, or even show/hide fields depending on the value of some other field. In the following example, we show a warning if the price is less than 20
and number of ingredients is greater than 6
:
Using this approach, you can add a nice touch to your UI and guide the content editor with additional logic, validate the input, and add other helpful elements which would otherwise be really difficult to define on the content model itself:
