Referencing and toggling mulitple regions from side bar.

Question

This is on APEX 32 10G XE.
My page looks like this
<--------------Sidebar Region------------>     <-------------------------------------------- A chart Region from link1--------------------------------->
|   _link1_                              |      |                                                                                                      |
|   _link2_                              |      |                                                                                                      |
|   _link3_                              |      |                                                                                                      |   
|   _link4_                              |      |                                                                                                      |
<-------------Sidebar Region------------>      <-------------------------------------------------------------------------------------------------------->My requirement is, the region on the right side is the chart region which will dynamically change based on the links selected in the sidebar.
To explain in a more elaborative way, if user clicks link1 from above, a chart will be displayed as a result of clicking link1, then, if user clicks link2, another chart should display as a result of clicking link2. And when that happens, previous region contents from link1 needs to disappear and chart region from link2 needs to show up as a result.
In summary, how can I dynamically hide/show multiple regions trigged by clicks on the links from side bar region on the left.
Any input?
Thank you much for reading this post.

No Problem Rich,
I'll try my best to explain it, if you can't quite get it work I see if i can sort out some screen shots,
1) Create New Region:
-->Go to your Page Definition and Create a new HTML region
-->Give it a Title and select No Template from the Region Template select list
-->Hit Create Region
2) Create a Hidden Page item:
-->From Page Definition Create New Page Item
-->Choose Hidden Item and Hidden and Protected for the item type
-->Give it a Name (i called mine P3_DISP_REG) and select a region
-->Accept defaults for the Label as this won't be displayed
-->Give the item a default value of 1
-->Hit Create Item
2) Add conditional display to the region:
-->From page definition edit your first region
-->In the Conditional Display Section --> Choose Value of Item in Expression 1 = Expression 2
+(this informs Apex to only the display the region if the value of the page item meets the value in expression 2)+
-->Type the name of the item you created in step 2 into Expression 1 e.g. P3_DISP_REG
-->In Expression 2 type the value of *1*
Repeat this for all regions increasing the value of expression 2 each time
3) Create list to change Item value:
-->Go to Shared Components and Select Create list
-->Give the list a name and accept rest of defaults +(this will take you to the list entries page)+
---->Hit Create List entry
-->Give the list entry a name +(i.e Corresponding Region Name )+
---->In the Target Section type in your page number
-->Then in Set these items Text field type (or select) your page item created in step 2 +(P3_DISP_REG)+
-->Then in With these Values type 1
this sets the value of the page item when the link is selected
Create the list entries for all regions on your page and type the corresponding value you typed in step 3 to display the correct region
4) Add the list to your page and your should be done!
Hope it helps
