One of the really nice features of APEX is the ability to hide / show regions when editing item or page attributes. This is really useful if you have to update the same attribute for multiple items.
If you want to implement this type of approach on a page you simply need to:
Create a New Region Template
Either create a new region template (or copy an existing one) and add a DIV tag with the id="XXX#REGION_STATIC_ID#" around the Definition Template.
Don’t forget to close the DIV at the end of the template. In this example I copied our region called “Reports Region” and named it “Reports Region 680 Width (Static ID)”
Create several regions on your page and assign a unique Static ID i.e. REGION1, REGION2 etc. Set the Region Template to the one you created in the 1.
Create a hidden item on the page called CURRENT_DIV
Finally edit the page attributes and place the following command in the “Page HTML Body Attributes” section:
And that’s it. The key thing to note here is that once a region is hidden, all form items are still active in the DOM and will be submitted along with all the visible form items. This is a great way to break out long, complex forms and enhance the user experience.
