Hi everybody Today I show you how to make a sticky brand header and avatars in Harmony. [image: 1IAJKUX.gif] Step-by-step We need modify 6 files: library.js, harmony.json, theme.tpl, harmony.tpl, brand.tpl, post.tpl to add 3 new settings: Sticky avatars (user avatars in the posts) Sticky header (brand header) Setting to show sticky header on mobile devices First we add a new settings in library.js Paste this code after this line stickyAvatars: 'on', stickyHeader: 'off', stickyHeaderMobile: 'off', Paste this code after this line config.stickyAvatars = config.stickyAvatars === 'on'; config.stickyHeader = config.stickyHeader === 'on'; config.stickyHeaderMobile = config.stickyHeaderMobile === 'on'; Now we need add translation for the new settings in harmony.json Paste this code after this line "settings.stickyAvatars": "Sticky user avatars in posts", "settings.stickyHeader": "Sticky header on desktop", "settings.stickyHeaderMobile": "Show sticky header on mobile", Next step, create controls of new settings in ACP and user profile in harmony.tpl and theme.tpl Paste this code after this line in harmony.tpl <div class="form-check form-switch"> <input type="checkbox" class="form-check-input" id="stickyAvatars" name="stickyAvatars" /> <label for="stickyAvatars" class="form-check-label">settings.stickyAvatars</label> </div> <div class="form-check form-switch"> <input type="checkbox" class="form-check-input" id="stickyHeader" name="stickyHeader" /> <label for="stickyHeader" class="form-check-label">settings.stickyHeader</label> </div> <div class="form-check form-switch"> <input type="checkbox" class="form-check-input" id="stickyHeaderMobile" name="stickyHeaderMobile" /> <label for="stickyHeaderMobile" class="form-check-label">settings.stickyHeaderMobile</label> </div> Paste this code after this line in theme.tpl <div class="form-check mb-3"> <input class="form-check-input" type="checkbox" id="stickyAvatars" name="stickyAvatars" {{{ if config.theme.stickyAvatars }}}checked{{{ end }}}> <label class="form-check-label" for="stickyAvatars">settings.stickyAvatars</label> </div> <div class="form-check mb-3"> <input class="form-check-input" type="checkbox" id="stickyHeader" name="stickyHeader" {{{ if config.theme.stickyHeader }}}checked{{{ end }}}> <label class="form-check-label" for="stickyHeader">settings.stickyHeader</label> </div> <div class="form-check mb-3"> <input class="form-check-input" type="checkbox" id="stickyHeaderMobile" name="stickyHeaderMobile" {{{ if config.theme.stickyHeaderMobile }}}checked{{{ end }}}> <label class="form-check-label" for="stickyHeaderMobile">settings.stickyHeaderMobile</label> </div> The finally we modify a theme files post.tpl and brand.tpl Replace the code in this line with a new code in post.tpl <div class="icon py-1 bg-body d-none d-sm-block {{{ if config.theme.stickyAvatars }}}position-sticky{{{end}}}" {{{ if config.theme.stickyAvatars }}}style="top:7.5rem;"{{{end}}}> Replace the code in this line with a new code in brand.tpl <div class="container px-md-4 brand-container {{{ if config.theme.stickyHeaderMobile }}}sticky-top{{{end}}} {{{ if config.theme.stickyHeader }}}sticky-lg-top bg-body pt-3{{{end}}}" {{{ if config.theme.stickyHeader }}}style="margin-top:-1rem;"{{{end}}}> /.nodebb build Happy Dev
