Hey there,
1. Please add the code below in your Appearance > Customize > Custom > CSS.
.x-portfolio-filters {
display: none;
}
.x-portfolio-filters-menu {
display: block !important;
}
2. This isn’t a feature offered by X. It could be possible with custom development, but this would be outside the scope of support we can offer. You may wish to consult a developer to assist you with this. X is quite extensible with child themes, so there are plenty of possibilities.
Thanks for understanding. Take care!
