Continuation of #10741. Field-level admin options, including the conditional logic and custom field components, are currently documented within the "admin > customizing views" page. This makes them hard to find because users, myself included, intuitively navigate to the fields overview doc first to locate this information. Now, they are rendered within "fields > overview" as expected. This should help keep the user from jumping around from doc to doc and getting lost.

The Code Field saves a string in the database, but provides the [Admin Panel](../admin/overview) with a code editor styled interface.

|
|
|
|
export const MyBlocksField: Field = {
|
|
// ...
|
|
type: 'code', // highlight-line
|
|
}
|
|
```

|
|
|
export const MyCodeField: Field = {
|
|
// ...

|
admin: { // highlight-line
|
|
// ...
|
|
},
