Timeline

Inspired by the timeline component in Timber, timelines can prove to be an interesting way of presenting a list of events in chronological order. This example is responsive; in allowing the layout to adapt for both small and wide screen widths. A website author is able to login, to add new entries to the timeline, using a loop element. The dates, event titles and descriptions are all editable using a combination of short text and long text elements.

Example

HTML & PHP

<ul class="timeline">
    <?php foreach ((new WYLoopElement())->aLoopIDs("Timeline Item") as $webyep_oCurrentLoop->iLoopID) { $loopid=$webyep_oCurrentLoop->iLoopID; $_SESSION["loopid"]=$loopid; $webyep_oCurrentLoop->loopStart(true,$webyep_oCurrentLoop->iLoopID); // WebYepV2 ?>
    <li>
        <div class="timeline_row">
            <div class="timeline_date">
                <?php webyep_shortText("Date", false, 550, 240); // WebYepV2 ?>
            </div>
            <div class="timeline_description">
                <h4 class="timeline_description_title">
                    <?php webyep_shortText("Title", false, 550, 240); // WebYepV2 ?>
                </h4>
                <p class="timeline_description_text">
                    <?php webyep_longText("Description", false, "", true, 600, 400); // WebYepV2 ?>
                </p>
            </div>
        </div>
    </li>
    <?php $webyep_oCurrentLoop->loopEnd(); } unset($_SESSION["loopid"]); // WebYepV2 ?>
</ul>
