help.: how to Exposed sort for view?

Hi
create a drop down for this or you can create a custom module or use a content type.
then call a javascript function in select box onchange event.
In that function call the view you are return using ajax.
if(A-Z) use 1 as argument else 0 as argument.then build a view based on that argument.

There are column sort options displayed by default for Table data; as part of the Basic Settings > Style configuration. If your data is not in a table or you do not want to use this method then you may have to create duplicate displays of your data within Views with different sort options and change displays when the user clicks on the menu options. When configuring the displays, set the menus up as Tabs, not Normal Menu Items, then they should appear like a horizontal sub-menu on the page. Have a look at this discussion (http://drupal.org/node/84369).

Hi,
This forum is for folks who are developing modules. Are you developing a module? Or are you simply trying to figure out how to use the existing "Views" module.

If you are simply trying to figure out how to use the "Views" module, you should post your question in the "Post Installation" forum :)
