Hi Dragos01,
You can go to the Backend > Site template styles > ja_blockk - Magz 1 > Layout settings > click edit for header-1 column then edit the header-1 block and remove the following code:
<div class="col-5 col-lg-2 t4-header-right d-flex justify-content-end align-items-center">
<jdoc:include type="element" name="theme-toggle" />
<jdoc:include type="element" name="megamenu-toggle" />
<div class="head-search">
<jdoc:include type="modules" name="head-search" />
</div>
</div>
And add the following CSS Code to the Tools > Custom CSS:
.t4-megamenu-wrap {
margin-left: auto;
}
