-====== Gallery Sample ====== +====== Gallery ====== 
-This is standalone application showing one way of using [[Dynamic Panel]].+ 
 +**Gallery** is a [[SOLoist Sample Applications|SOLoist sample application]] for a classical editable picture gallery. This is a simple, standalone application that demonstrates one way of using a [[Dynamic Panel]]. 
 + 
 +By choosing an object of //House// from the suggest box, the gallery of pictures associated with that object is displayed. 
 + 
 +A click on a thumbnail shows the full-sized picture. This functionality relies on an external JavaScript code, [[http://fancybox.net|FancyBox]], easily incorporated in the rest of the SOLoist code. 
 + 
 +A click on the disclosure panel expands the form for adding new pictures to the gallery. 
 + 
 +Pictures in the gallery can be reordered (by entering their order numbers in the boxes) and removed (by clicking on an X sign).
