Are there any tricks to toggling the visibility of a field client-side? (Field is added in a `beforeLoad` user event if that matters).  I have it start off hidden and only want to make it visible later on if certain conditions are met client-side.
```
const field = ctx.currentRecord.getField({ fieldId: 'custpage_item' });
field.isDisplay = true; // does not work
field.isVisible = true; // does not work
```

I have this setup in a custom module as you need the use.updateFieldDisplayType({options})

You need to pass in the options of the type and true or false.

Oops I wasn't clear that I'm trying to change the visibility client side
and far as I can tell `updateFieldDisplayType` is only available to server scripts as part of the `N/ui/serverWidget` module :slightly_frowning_face: 

I decided to just leave have it start off disabled and then enable it using `field.isDisabled = true` which works fine.

I am doing loads of hiding and showing in client script on the customer form for application fields and I for the life of me cannot remember what I am using to do it. If I was at my computer I could tell you straight away. I will let you know tomorrow as it tool me ages to figure it out. I have them built in a custom module so i can just call them easier when needed.

<@U8CT0V220> I have this setup in my custom module like the below.
```function disableField(currentRecord,myFieldID,truefalse) {
		var disable = currentRecord.getField({fieldId: myFieldID}); // myFieldID is the second parameter passed through on the function from the client script.
		disable.isDisabled = truefalse; // disable said field
	}```
```function displayField(currentRecord,myFieldID,truefalse) {
        var display = currentRecord.getField({fieldId: myFieldID}); // myFieldID is the second parameter passed through on the function from the client script.
        display.isDisplay = truefalse; // hide said field
    }```
```function makeMand(currentRecord,myFieldID,truefalse) {
        var makeMand = currentRecord.getField({fieldId: myFieldID}); // myFieldID is the second parameter passed through on the function from the client script.
        makeMand.isMandatory = truefalse; // hide said field
    }```

Thanks.  Looks like `isDisplay` *should* work (in theory).  I think my case might be different because I started it off hidden server side (and would only become unhidden client side).

I ended up compromising by starting it off disabled server side (and later enabling it client side), which works for what I need
