Install this theme component
Overview
This simple theme component automatically indents all subcategories in the sidebar - works in desktop, tablet and mobile viewport sizes.
There is one setting to change the indent size - the default is 1em, minimum 0.5em and maximum 3em.
Settings:

Notes
This theme component is only intended for single level subcategories. If your forum has sub-subcategories enabled, this component will probably break, or at least not look very good in your sidebar.
This component replaces the now deprecated Indented / Nested Sidebar Categories or Subcategories .

nice job! It will be wonderful if it can fold or unfold for the parent categories. Is it possible?

Nice work Lilly - delightfully simple and effective. A marked improvement!!
Also, I love the clear admin notice about it.

It would be useful to have the option to indent on mobile too

I agree - and hadn’t noticed that it doesn’t until you pointed it out just now!
@Lilly , did the old TC indent on mobile?

What was the thought/reason for deprecating a more full featured component (Nested categories) in favor of this one with less control?
Can I keep using the old one even though it’s deprecated or is it going to eventually break?

Ahah - it indents fine in portrait, but not in landscape (using an iPad)

works on my ipad
let me guess, it’s doing that two-column sidebar view?
Ahah - sorry, forgot to mention my custom CSS forces it to single column on mobile. It works fine in portrait (indented like desktop) but is a plain-flat list in landscape

this is what i see on my iPad in both landscape and portrait views:
i think firefox view was sometimes weird on tablet with 2-columns. i pushed a fix that should force it to use single column all the time.

Ah -it’s working for me now too, sorry! It seems to go “flat” when you rotate the device - but fixes itself if you refresh. Thanks for checking!!
