Change icon for progressbar

Can I change icon for progressbar for filemanager? Or how I can disable progressbar for all actions - open branch, uploading and other?

You can customize .webix_progress_icon .webix_progress_state css rules and use .gif image instead of FontAwesome icon.

For example

  .webix_progress_icon { display:none }

Can I show/hide this progressbar by event?

There are two related methods: show/hideProgress():

Can you provide an example of using a gif instead of an icon?

Hello @Natalya ,
You can redefine .webix_progress_icon .webix_progress_state CSS rule and use gif icon as background.
Here is the example:
