hi @DylanIslington I have used this approach in few projects several ways but I can now find only one but it is I think some way close what you are after.
here is request.
there is a one collection called “artists”. Create dynamically alphabet and to each letter add artist whose name start with letter from alphabet.
Means I had to select Artis based on condition and add these into fragment that as added to DOM behind letter.
This was request from client but she never come back so here is this RO - example to see how documentFragment works.
here it is Live
I have another code snippet where I use it as filter but I can’t find project where was used.
hope this will give you some ideas how to
now you have several ways to achieve your goals
