Add Hide Table Columns for categories and images

[MrMusic]

Since joomla 4.2 there is a nice feature to hide any column in the table views: joomla/joomla-cms#36591

@szepty-ziemi had already suggested the implementation at the last online meeting.
Surprisingly, the implementation in the JoomGallery was very simple.
Used for categories and images view because in tags and configuration view there are only a few columns.

1. Dropdown column list causes to scroll bar to appear on the image/categories list

• go to image / category manager
• click column button

RESULT

• dropdown cause scrollbar to appear

EXPECTED RESULT

• dropdown should appear and be visible, no scrollbar displayed

Issue do not appear if there is enough items on the list, and list is longer than dropdown.

2. There is unnamed checkbox for list item checkbox column. It apply to image column

• just click on column selector to display dropdown

Issue apply to both Image and Category manager. Maybe we should have this column named in the list header (No sorting is needed here)?

While testing on Windows, I encountered issue right after installation.

• Install JG package
• go to Image Manager or Category manager

Only those two places are affected. All other e.g Configuration Manager are ok.

Done.

I cannot reproduce this. Did you perform a new installation after deinstallation?

This effect is due to the fact that other classes are currently used in JoomGallery than in the corresponding Joomla views. I don't know if this is intentional?
Now i changed the classes for the images and categories view so that it is the same as in the Joomla views.
Maybe this will have any negative effect?

The only possible reason for me: You are not using Joomla 4.2.x but an older version.

[szepty-ziemi]

@MrMusic BINGO! That was the source of issue. Upgraded to latest version and issue was gone.

[szepty-ziemi]

I confirm that latest commit was tested on both Linux and Windows. Everything works and looks good.

Whats the reason for removing the "table-striped" class?

[Elfangor93]

And the div with class "table-responsive" I would leave there anyway. In that way there is a horizontal scroll bar if to many rows are visible for the current screen width.

[MrMusic]

I have changed the classes so that it is the same as in Joomla.
The missing scrollbars are actually a disadvantage here.
Now i have reversed it.

@MrMusic Since you are changing only the template files of images and category manager, I can not see any negative side effects except for the fact that it is displayed differently as the first implementation was suggested.

Sorry, the fix also prevented the horizontal scrollbars from appearing. so i had to reverse it.
