Using this in PHP to display the Joomla search tools
<?php echo LayoutHelper::render('joomla.searchtools.default', array('view' => $this, 'options' => array('filtersHidden' =>$hidden))); ?>
and getting this result
where it should display like this
I can get the search icon to line up with the search field using something similar too what you gave me for the same problem in the calendar field with this CSS
.js-stools-container-bar .input-append {display:flex;}
but I can't get the remaing two items to be on the same line
