APEX Navigation Menu Experiments Part 3

Published Tuesday, March 31, 2020 by John Snyders

This is the third and final article in the navigation menu experiments series. Check out parts 1 and 2. In this experiment the navigation menu dynamically changes between side and top positions.

As in parts 1 and 2 this sample app was created using the upcoming 20.1 APEX release but the techniques should work on previous releases. On apex.oracle.com there is currently a pre-release of 20.1 where you can try out the app (enter any username). You can also download the app and import it into your own workspace on apex.oracle.com or your own 20.1 instance once available.

This third experiment was motivated by this question on the APEX forum. They asked

“How can I dynamically change the position of the navigation menu, from top to side or vice versa …”

I believe the intent is related to being responsive to different screen sizes. The side navigation is already responsive in that it is collapsible. The menu bar and sub menus work fairly well on small mobile screens although there are some things that could be improved.

APEX Navigation Menu Experiments Part 2

Published Friday, March 20, 2020 by John Snyders

This is part 2 in a series of articles exploring navigation techniques in Oracle Application Express. Check out part 1 first if you missed it. Here I will show how to dynamically fetch new child nodes in the navigation tree on-demand.

The sample app for part 2 was created with the upcoming 20.1 APEX release but the techniques should work on previous releases. On apex.oracle.com there is currently a pre-release of 20.1 where you can try out the app (enter any username). You can also download the app and import it into your own workspace on apex.oracle.com or your own 20.1 instance once available.

APEX Navigation Menu Experiments Part 1

Published Monday, March 16, 2020 by John Snyders

Out of the box APEX provides a number of useful, declarative, good looking navigation options. There is the side navigation menu tree and the top navigation menu bar, top navigation tabs, and new in release 20.1 top navigation mega menu.

In this series of articles I will be discussing some advanced use cases primarily related to side navigation. These are based on customer requests and my own musings. The sample app for part 1 was created with the upcoming 20.1 APEX release but the techniques should work on previous releases. On apex.oracle.com there is currently a pre-release of 20.1 where you can try out the app (enter any username). You can also download the app and import it into your own workspace on apex.oracle.com or your own 20.1 instance once available.

This topic interests me because, although I don’t work on the global navigation features in general, I created the treeView widget used for side navigation and the menu widget used for top navigation. I have written about navigation topics before but exclusively related the menu widget. In More APEX Menu Fun I wrote about how to create a menu bar with custom markup (mega) popup menus. Before there was a built-in mega menu option I showed how to create one in APEX Media List Mega Menu. I then refined the mega menu example and included more custom content menu examples in All The Things That Pop Up.
