Summary

The "List All Categories in an Article Category Tree" menu item no longer includes the "Number of Columns" (num_columns) setting in the Blog Layout tab in Joomla 4.x and 5.x. This field existed in Joomla 3.x.

Steps to reproduce the issue

1. Go to Menus → Add new menu item
2. Select Menu Item Type: List All Categories in an Article Category Tree
3. Check the "Blog Layout" tab → no option to set number of columns

Expected result

There should be a field to configure the number of columns, just like in Joomla 3.x. The parameter num_columns is still functional if manually added to the params field in the database (e.g. "num_columns":"3"), and the frontend renders it correctly.

Actual result

There is no UI to set the number of columns, even though the parameter is still respected on the frontend.

System information (as much as possible)

• Joomla version: 4.4.x / 5.3.0 (tested)
• PHP version: 8.3.20
• Template: T4 Framework (T4_bs5_blank)
