hey klutzon, if you go back and read the first 2 pages of this thread, you'll see that "jjj2" has posted a solution showing this Ajax/inline "Ask a question" form within MagicTabs.
The hide/show is controlled by 4 statements:
1. When the form is first shown, it is hidden by this CSS statement:
div.ask_inline {
display:none;
You can remove this (or comment it out as jjj2 did).
2. When the user clicks "Ask a question ...", the form is revealed by that actual link:
<a class="button" href="" onclick="document.getElementById('ask_inline').style.display='block';return false;"><?php echo $ask_seller_text; ?></a>
If you haven't already, remove that and make it your tab title.
3. After the email is sent, this JavaScript line re-hides the form:
document.getElementById('ask_inline').style.display='none';
Again, remove or comment out. jjj2 left it in, I guess so that the user sees it disappeared, confirming in the user's mind that the email was sent.
4. If the user starts to fill out the form, and then changes his/her mind and clicks "Cancel", this action re-hides the form:
<input type="button" name="cancel" class="button" value="<?php echo $VM_LANG->_('CMN_CANCEL'); ?>" onclick="document.getElementById('ask_inline').style.display='none'; return false;">
You may wish to replace that with an HTML form "Reset" button.
