No one can help me. .
.addClass('icon-plus-sign').removeClass('icon-minus-sign');
This is adding style and removing style. Use show() and hide() in jq to show and hide

.addClass('icon-plus-sign').removeClass('icon-minus -sign');
This is to add styles and remove styles. Show() and hide() are used in jq to show and hide
I will give you CSS and you can see. They are used to replace the expansion and contraction plus and minus icons. The css of icons are all icons.
