Hi again.
There are 2 cases:
- If you want to change the width to less than 200px, please add the following css rule to the custom.css (templates/t3_bs3_blank/css) file:
.t3-megamenu .mega > .mega-dropdown-menu {
min-width: 200px;
}
change the min-width value to whatever you want.
- If you want to make the width wider, in the megamenu setting panel, select the sub-megamenu and change the width (in pixel), check the screenshot:
