@copilot I dont see how Im supposed to edit in the UI

@copilot I dont see how Im supposed to edit in the UI

To edit properties in the UI, double-click on any editable cell in the data grids:

For Content Items:

1. Navigate to the Content tab and expand any content item
2. Double-click on values in the "Value (double-click to edit)" column
3. Edit the text and press Enter to save
4. A "Modified" badge will appear on edited properties

For Content Type Properties:

1. Navigate to Content Types and expand a type
2. Double-click on cells in columns marked "(editable)": Edit Caption, Searchable, Required, or Localizable
3. Edit the value or toggle the checkbox

I've added visual hints in commit 6b5a0b9:

• Edit icon with tooltip in the header explaining the double-click action
• Column labels showing "(editable)" or "(double-click to edit)"
• Tooltips on the edit icons with instructions

The double-click interaction is standard for MudBlazor's DataGrid cell editing mode.

@copilot Nothing happens when I double-click

You're right - the double-click editing wasn't working. I've fixed this in commit 1a0cdf6 by replacing it with explicit edit buttons.

New editing workflow:

For Content Properties:

1. Expand a content item to see its properties
2. Click the edit icon (✏️) in the "Actions" column next to any property
3. Edit the value in the inline text field
4. Click the checkmark (✓) to save or X to cancel

For Content Type Properties:

1. Expand a content type
2. Click the edit icon dropdown menu in the "Actions" column
3. Select what to edit (Edit Caption, Toggle Searchable, etc.)
4. Edit the value or toggle the checkbox
5. Click the checkmark (✓) when done

The issue was that MudBlazor's EditMode="DataGridEditMode.Cell" doesn't work with TemplateColumn elements. The new approach uses explicit edit state management with visible edit/save/cancel buttons, making the editing feature much more discoverable and reliable.

@copilot looks good, but it requires scrolling manually to the far right to see the edit-button. We need to update the look so the button is not hidden.

@copilot looks good, but it requires scrolling manually to the far right to see the edit-button. We need to update the look so the button is not hidden.

Fixed in commit 81d8071. The Actions column is now the leftmost column in both grids, making the edit button immediately visible without any scrolling.

Column order now:

• Content Properties: Actions | Badges | Name | Value
• Content Type Properties: Actions | Type | Name | Edit Caption | Searchable | Required | Localizable

The edit icon (✏️) is now always visible in the first column of each row.
