    <p>I load one list of objects in JQuery autocomplete combobox and when I select one from the list it goes in table of selected objects. </p> <p>I want when I finish that to set my JQuery combobox to first value (empty). How to do that?</p> <p>Here is the code for combobox. I just added call for function addRow() to add me row to table automaticly when I press enter or select value from the list:</p> <pre><code>(function( $ ) { $.widget( "ui.combobox", { _create: function() { var self = this, select = this.element.hide(), selected = select.children( ":selected" ), value = selected.val() ? selected.text() : ""; var input = this.input = $( "&lt;input&gt;" ) .insertAfter( select ) .val( value ) .autocomplete({ delay: 0, minLength: 0, source: function( request, response ) { var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" ); response( select.children( "option" ).map(function() { var text = $( this ).text(); if ( this.value &amp;&amp; ( !request.term || matcher.test(text) ) ) return { label: text.replace( new RegExp( "(?![^&amp;;]+;)(?!&lt;[^&lt;&gt;]*)(" + $.ui.autocomplete.escapeRegex(request.term) + ")(?![^&lt;&gt;]*&gt;)(?![^&amp;;]+;)", "gi" ), "&lt;strong&gt;$1&lt;/strong&gt;" ), value: text, option: this }; }) ); }, select: function( event, ui ) { ui.item.option.selected = true; addRow(); self._trigger( "selected", event, { item: ui.item.option }); //cambiaPrestazione(ui.item.option.value); }, change: function( event, ui ) { if ( !ui.item ) { var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( $(this).val() ) + "$", "i" ), valid = false; select.children( "option" ).each(function() { if ( $( this ).text().match( matcher ) ) { this.selected = valid = true; return false; } }); if ( !valid ) { // remove invalid value, as it didn't match anything $( this ).val( "" ); select.val( "" ); input.data( "autocomplete" ).term = ""; return false; } } } }) .addClass( "ui-widget ui-widget-content ui-corner-left" ); input.data( "autocomplete" )._renderItem = function( ul, item ) { return $( "&lt;li&gt;&lt;/li&gt;" ) .data( "item.autocomplete", item ) .append( "&lt;a&gt;" + item.label + "&lt;/a&gt;" ) .appendTo( ul ); }; this.button = $( "&lt;button type='button'&gt;&amp;nbsp;&lt;/button&gt;" ) .attr( "tabIndex", -1 ) .attr( "title", "Show All Items" ) .insertAfter( input ) .button({ icons: { primary: "ui-icon-triangle-1-s" }, text: false }) .removeClass( "ui-corner-all" ) .addClass( "ui-corner-right ui-button-icon" ) .click(function() { // close if already visible if ( input.autocomplete( "widget" ).is( ":visible" ) ) { input.autocomplete( "close" ); return; } // work around a bug (likely same cause as #5265) $( this ).blur(); // pass empty string as value to search for, displaying all results input.autocomplete( "search", "" ); input.focus(); }); }, destroy: function() { this.input.remove(); this.button.remove(); this.element.show(); $.Widget.prototype.destroy.call( this ); } }); })( jQuery ); $(function() { // $( "#styleIdPrestazione" ).val("-1"); $( "#styleIdPrestazione" ).combobox(); $( "#toggle" ).click(function() { $( "#styleIdPrestazione" ).toggle(); }); }); }); </code></pre>

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.
