| Code snippet for adding essays filtering by labels | |
| using Liquid language and Semantic UI for e.g. to | |
| TechFolios portfolio http://techfolios.github.io/ | |
| --> | |
| <!-- Single essay card example from TechFolios --> | |
| <a class="grey card myessay" href="{{ site.baseurl}}{{ include.page.url }}"> | |
| <div class="content"> | |
| <span class="header">{{ include.page.title }}</span> | |
| <div class="meta"> | |
| <span class="date">{{ include.page.date | date: "%d.%m.%Y" }}</span> | |
| </div> | |
| <div class="description center aligned" style="font-size: 13px;"> | |
| {{ include.page.summary }} | |
| </div> | |
| </div> | |
| <div class="extra content"> | |
| <div class="ui tiny labels"> | |
| {% for label in include.page.labels %} | |
| <div class="ui custom-color label">{{ label }}</div> | |
| {% endfor %} | |
| </div> | |
| </div> | |
| </a> | |
| <!-- Step 1 --> | |
| <!-- Prepare & feed label picker --> | |
| <div class="" style="margin-bottom: 5%;"> | |
| {% assign essays = site.pages | where: "type", "essay" %} | |
| {% assign labels = '' | split: '' %} | |
| {% for essay in essays %} | |
| {% for label in essay.labels %} | |
| {% assign tmp = label | split: '_' %} | |
| {% assign labels = labels | concat: tmp %} | |
| {% endfor %} | |
| {% endfor %} | |
| {% assign labels = labels | uniq | sort %} | |
| <select id="labelPicker" multiple="multiple" name="skills" class="ui fluid search dropdown"> | |
| <option value="">Pick label(s)</option> | |
| {% for label in labels %} | |
| <option value="{{label}}">{{ label }}</option> | |
| {% endfor %} | |
| </select> | |
| </div> | |
| <!-- Step 2 --> | |
| <!-- Prepare hide class for hiding essays instead of using display attribute --> | |
| <!-- idea comes from: https://css-tricks.com/places-its-tempting-to-use-display-none-but-dont/ --> | |
| <style> | |
| .hide { | |
| position: absolute !important; | |
| top: -9999px !important; | |
| left: -9999px !important; | |
| } | |

| <!-- Step 3 --> | |
| <!-- Add JS script for filtering management --> | |
| <script> | |
