Is there a way to make it so only the original poster avatar is shown on topic post instead of latest reply? This would be for mobile only.

both of these work on mobile and desktop. adds the author column and has option for the latest poster in posters column: [image] Topic List Author & Posters Theme component information_source Summary Adds a topic author to the left column of topic list pages, as well as an option to only display most recent poster in the default posters column. Author avatar can also be sized and shaped. eyeglasses Preview https://discourse.theme-creator.io/theme/Lilly/discourse-topic-list-author-posters hammer_and_wrench Repository https://github.com/Lillinator/topic-list-author-posters question Install Guide How to install a theme or theme component I… Adds the author column and removes the posters column: [image] Topic List Author Theme component information_source Summary Makes the topic author appear instead of posters and allows changing the placement of the author column in topic list pages. hammer_and_wrench Repository https://github.com/discourse/discourse-topic-list-author eyeglasses Preview Preview on Discourse Theme Creator question Install Guide How to install a theme or theme component open_book New to Discourse Themes?

oh, I’d actually want that on desktop too! in my support community who posted initially is more important than who responded last…

Hmmm so I tried the first two theme components last night and display-wise didn’t manage to just « replace » one avatar with the other, it didn’t look right at all in both Air Theme and Horizon. Will try again and make screenshots but just wanted to give a heads-up!

i don’t program for horizon, sorry. those first two won’t work with it. Discourse has made horizon pretty uncustomizable. i believe horizon already shows the author and last poster by default? they should work with air theme tho. i can test when i have time :slight_smile: you are going to find that not all themes and theme components are compatible with each other, so you will have decisions to make in that regard. :woman_shrugging:t2:

nope. but sometimes i note it if i know [image]Topic List Author & Posters Not really compatible with horizon theme. :slight_smile:

i had a quick look and adding this code to the css of a local custom component will fix it for you if you are using the Topic List Author theme component. .full-width .contents .topic-list .topic-list-body .topic-list-item .topic-list-data.posters { display: none; } .custom-author-column { display: flex; align-items: center; justify-content: center; }
