If you mean a public gallery or public generators or such, you’d need to add the script details yourself but you could shlap something like this in.

<!-- sample search thingy -->

<!-- sort filter section -->
<div style="margin: auto; display: flex; justify-content: center; align-items: center; flex-wrap: wrap;">
  <span class="mainctls sortctl" style="margin-left: 8px; font-family: inherit; color: red;" >
    <select id="sortSelect" onchange="handleSort(this.value)">
      <option value="default" selected>Sort</option>
      <option value="a-z">A-Z</option>
      <option value="z-a">Z-A</option>
      <option value="dateCreated">Date Created</option>

Nice simple generic search thingy, but then you kinda have to hope that they have tags or references to filter. This is just a scuffy sample but, its a simple start if you want to use it and work from. You need to populate the handleFilter(this.value) and handleSort(this.value) to work depending on how you want to use it, i left them empty so you can work away with it.

How do we sort that? From A-Z ?
