Hello
how can i remove home4 techone search and category (blue line)
thank you
You can do that via CSS.
Try to add this CSS in Dashboard > Appearance > Customize > Additional CSS :
.main-header .form-search {
display: none;
}
If you have more questions, the best way is contact the theme author. I think this is your item, and there you will find a button - βGo to item supportβ.
