In Jquery UI selectable plugin, I want to be able to select multiple cells in different portions of a massive table grid. Normally, clicking on one item will deselect other items, unless the user also holds down a modifier key. You can see this behavior on the jQuery Selectable demo. How can I prevent deselection of highlighted cells on mouse up without using the keyboard?

An example - on jsfiddle for instance - would be much easier for us to picture your problem.Didier Ghys– Didier Ghys2012-03-09 21:36:45 +00:00Commented Mar 9, 2012 at 21:36

@Didier Ghys- what I want is here:jqueryui.com/demos/selectable/#display-grid except that it deselects previous selection on mouse up and selecting a new cell.Deepa Thalikar– Deepa Thalikar2012-03-09 21:58:47 +00:00Commented Mar 9, 2012 at 21:58

1Multiple selections can be achieved ... while holding the Ctrl/Meta key, [allowing for multiple (non-contiguous) selections].Didier Ghys– Didier Ghys2012-03-09 22:00:23 +00:00Commented Mar 9, 2012 at 22:00

One possible solution:
<style>
#feedback { font-size: 1.4em; }
#selectable .ui-selecting { background: #FECA40; }
#selectable .ui-selected { background: #F39814; color: white; }
#selectable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
#selectable li { margin: 3px; padding: 0.4em; font-size: 1.4em; height: 18px; }
</style>
<script type="text/javascript">
$(function() {
$("#selectable").bind("mousedown", function(e) {
e.metaKey = true;
}).selectable({
stop: function() {
var result = $( "#select-result" ).empty();
$( ".ui-selected", this ).each(function() {
var index = $( "#selectable li" ).index( this );
result.append( " #" + ( index + 1 ) );
});
}
});
});
</script>
<p id="feedback">
<span>You've selected:</span> <span id="select-result">none</span>.
</p>
<ol id="selectable">
<li class="ui-widget-content">Item 1</li>
<li class="ui-widget-content">Item 2</li>
<li class="ui-widget-content">Item 3</li>
<li class="ui-widget-content">Item 4</li>
<li class="ui-widget-content">Item 5</li>
<li class="ui-widget-content">Item 6</li>
</ol>
