Hello,

Drag&drop the categories to reorder them the way you like. Click on edit link to edit the category
Unfortunately, there is a permanent problem with Osclass
When dragging, a message appears
  This action could take a while.
and nothing happens
Multiple browsers have been used
Google Chrome
Firefox
Edge
The same problem
Is there a way to add a list order button instead of dragging

@rooman
review network tab and console in your browser

Thank you
The problem is in the jquery-ui.min.js file
oc-includes\osclass\assets\js\jquery3\jquery-ui
Library Version Old v1.12.1
Vulnerability Count 3
Highest Severity High
I upgraded to 1.13.2
This was the cause of the problem
It is better to fix the problem in the new update 8.0.3

Thanks

Then I suppose your browser was blocking that?
