@brianteeman I've just tested it before I wanted to merge but I've noticed something:

In categories list view for com_content everything works fine, but in categories list view for com_contact only categories of com_content are available for selection in the new categories filter field.

So it seems I always can select only com_content categories, regardless in which component's categories view I am.

I used testing sample data on current 4.0-dev.

Can you check and confirm or let me know if I'm doing something wrong?

And what is desired behavior of the new filter: Always be able to select from all categories, regardless of component (not nice), or should it be aware of the component and only offer suitable categories for the particular component for selection (perfect)?

I confirm the issue. Setting back to pending.

Note: I also have issue merging this PR in my local repo. Had to pick up the file from PR branch.

I guess the issue may be in the xml where the filter is limited to com_content

<field
			name="category_id"
			type="category"
			label="JOPTION_SELECT_CATEGORY"
			multiple="true"
			extension="com_content". /// Limited to com_content
			layout="joomla.form.field.list-fancy-select"
			hint="JOPTION_SELECT_CATEGORY"
			onchange="this.form.submit();"
			published="0,1,2"
		/>

But it looks also that the branch may not be up to date.

I propose to make the extension dynamic

		<field
			name="category_id"
			type="category"
			label="JOPTION_SELECT_CATEGORY"
			multiple="true"
			extension="dynamic"
			layout="joomla.form.field.list-fancy-select"
			hint="JOPTION_SELECT_CATEGORY"
			onchange="this.form.submit();"
			published="0,1,2"
		/>

@infograf768 Set the attribute in the model.

@brianteeman getStoreId() method in the model also needs to be updated.

@brianteeman Why closing? Will you make a new PR instead?
