Can you tell me in one sentence when I would use it?
HijaxGrid holds many different HijaxBlocks, and displays them when a Hijax-enabled link is clicked on.
As for when you would want to use it - that greatly depends on what kind of layout you are building and what you want to accomplish. There are too many examples of how to use HijaxGrid to answer a “when use it” question in a single sentence.
In general, I keep a HijaxGrid close to the link which activates the content displayed in a HijaxGrid. For example, if you have a link near the top of the page, but the HijaxGrid is way down at the bottom, then even after clicking on the link visitors may not realize that content has been revealed on the page.
So, if I have a group of links (image thumbnails, whatever) together in a section, I’ll place a HijaxGrid near them (with the relevant HijaxBlocks inside), so that when the links are clicked on the content is revealed close by.
To sum up:
- HijaxGrid holds many HijaxBlocks
- You’ll create Hijax-enabled links which point to the HijaxBlocks inside that HijaxGrid
- I recommend keeping the HijaxGrid close to where the links are
Hope this helps.
