Using jquery ui datepicker, i used to do this
beforeShow: function( input, obj ) {
setTimeout(function() {
var buttonPane = $( input ).datepicker( "widget" ).find( ".ui-datepicker-buttonpane" );
$("#BCL").hide();
$("#BTDY").hide();
$( "<button>", {
text: "Clear",
click: function() {
$(input).val('');
}
}).addClass('ui-state-default ui-corner-all').appendTo( buttonPane );
}, 1 );
},
The code above add a clear button to clear date selection.
How to do this in for yii\jui\DatePicker?
