APEX Splitter Plugin

You’ve been using the Splitter plugin for maybe years without realising it. No? Well if you’ve used APEX Page Designer on version APEX 5 and above you’ll notice the page is split in to several resizable panes. Below is my APEX Page Designer view. You can see that it has been vertically split in to a left, middle, right arrangement with the middle pane split horizontally with a top and a bottom pane.

If you want, you can put this in to Two Pane mode using Spanner > Layout > Two Pane Mode

Whatever your arrangement; the page is split. But what if we want to use the same functionality and split our applications in the same way? … The answer is the Splitter Plugin.

You won’t find this plugin to download from the usual sources; To get it functional in to your application involves a few steps…

Please be aware: The below steps adds a dependency in your application to an undocumented internal APEX component. This internal component was intended for Page Designer only. Using this may cause support/upgrade issues in your application and therefore this method is not advisable for production applications.

1. Import APEX Page Designer from the apex\builder\ f4000.sql file from your APEX download zip file
2. Export the Splitter plugin from shared components
3. Import the Splitter plugin to your application
4. Grant execute on APEX_180100.WWV_FLOW_F4000_PLUGINS to your parsing schema
5. Edit the plugin and prefix the Callback Function names with APEX_180100

Once you have that sorted, you can use the Splitter Plugin as you would a native Region Type. There are some rules I have found.

1. A Splitter region should have two and only two sub regions
2. One of those directly referenced sub regions cannot be another splitter (although a grandchild sub region can be a splitter)
3. The Splitter region works much better using the Blank with Attributes (no grid) Template
4. The Splitter region must have a width (use a Custom Attribute to set the width)
5. The Splitter attributes must have a position away from the edge (you can choose which edge)

In my example below, I try to somewhat recreate the look of the Page Designer to prove the concept of what can be achieved.
Unfortunately, I cannot host on apex.oracle.com because I am unable to grant the required privilege on the internal APEX package.
