    <p>I modified the show_dropdown function to automatically determine if it should display above or below:</p> <pre><code>function show_dropdown() { if (input_box.is(':focus')) { var windowHeight = $(window).height(); var docViewTop = $(window).scrollTop(); var dropdownPosition = $(token_list).offset().top + $(token_list).outerHeight(); var availableSpace = windowHeight - (dropdownPosition - docViewTop) var borderWidth = parseInt(dropdown.css('border-bottom-width')); if (availableSpace &gt;= (settings.maxHeight + 2 * borderWidth)) { dropdown.css('bottom', ''); $('body').css('position', ''); dropdown.css({ 'border-top-width': 0, left: $(token_list).offset().left, top: $(token_list).offset().top + $(token_list).outerHeight() }); } else { dropdown.css('top', ''); var bodyHeight = $('body').outerHeight(); var bodyTop = $('body').offset().top; var bottom; if ((bodyHeight + bodyTop) &lt; dropdownPosition) { bottom = dropdownPosition - (bodyTop + bodyHeight) ; } else { bottom = (bodyTop + bodyHeight) - ($(token_list).offset().top + borderWidth); } dropdown.css({ 'border-top-width': borderWidth, 'border-top-color': dropdown.css('border-bottom-color'), 'border-top-style': dropdown.css('border-bottom-style'), 'bottom': bottom, 'left': $(token_list).offset().left - parseInt($('body').css('margin-left')), 'position': 'absolute' }); $('body').css({ 'position': 'relative' }); } dropdown.css({ maxHeight: settings.maxHeight, overflow: 'auto', zIndex: settings.zIndex }).show(); } } </code></pre> <p>I've also added a <code>maxHeight</code> property to tokenInput and use it to both check for space and set the size of the dropdown.</p> <p>Try it out here: <a href="http://jsfiddle.net/colin_young/dvuHD/19/" rel="nofollow">http://jsfiddle.net/colin_young/dvuHD/19/</a> (note that my version has some significant modifications from the stock version, I just haven't had a chance to create pull-requests for them).</p> <p>No attempt is made to ensure there is space above however. The assumption is that if there is no space below and none above there isn't a lot you can do, although centering on the input element might be a good compromise.</p>

    1. COI should note that my solution has some positioning issues, so it's not a completely generic one. You need to test it in your specific implementation.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
