I don’t think there is a built in way, but you can achieve this with some simple CSS.
I think it’s even less involved than what I describe below if you are applying it to ALL top level categories. Try adding this to your theme’s Common CSS first:
// Remove the New Topic button from all top-level categories
More involved way
First you’ll need to find the category slug of the top-level categories (Note: This is strictly for top-level categories. Sub-categories are a little different.)
For example, if we take the URL for the support category here on Meta:
The slug is whatever is after the
/c/part of the URL. In this case it’s
support. If your category has multiple words in it, it will have dashes like
The CSS will be looking for a class that starts with
category- and continues with the slug of the top-level category. So for the above examples, you would use
So with that in mind, you can customize the following CSS to fit your needs, and add it to the Common CSS section of your theme:
You can add more to the top of the list, just be sure to include period at the beginning and the comma at the end.
If you’ve never worked with CSS, this might be a little confusing, so feel free to ask for any further clarification.
