Show Thread Enhancements - ThreadNav: scrolling New Posts navigation bar for Showthread

ThreadNav(2.1) puts almost all the information in New Posts or Today's Posts in a compact scrolling navigation bar in the thread display page (showthread). The location in showthread depends on the user's thread viewing settings. Buttons on either end scroll the list of new posts right or left and additional information is available in a drop down box when you hover over the lower portion of the post cell. The list automatically refreshes using AJAX once a minute (default).

In Version 2.1 you can now place ThreadNav in any vBulletin page. A simple setting will put it in Forum Home (index) and it can be added to other pages with a simple template edit (See instuctions in ThreadNav settings in your AdminCP for edits).

Updated Version 2.1
I've updated this recently to make it fully compatible with updates to Thread & Forum Ignore System, if it is installed. I also got rid of the text jiggle in some browsers when you hover over a cell to display the drop box.

Features:

General:

• Searches for New Posts or Today's Posts
• List scrolls right or left with buttons at ends
• Automatically refreshes once a minute (default setting)
• Cell width adjusts automatically to fit available space
• Hovering over lower portion of partially exposed cell
  snaps the cell into full view
• Automatically integrates with Thread & Forum Ignore System
  if installed

In the cell for each thread:

• Go to first unread post button (New Posts only)
• Thread link goes to either first or last post depending
  on user settings for viewing threads
• Name of last poster
• Last post button

In the drop down box:

• Date/time
• Forum
• Thread starter
• Peplies
• Views
• Links for previewing first and last posts

User settings:

• Turn ThreadNav off
• Get New Posts
• Get Today's Posts

Admin Control Panel:

• On/off
• Other pages to show ThreadNav
• Set refresh interval
• Maximum minutes ThreadNav will continue refreshing
• Allow or disallow guests to see ThreadNav
• Maximum number of posts to show
• Minimum width of each post cell.
• Excluded forums

Upgrading to version 2.0

• Upload the new product xml file in Plugins & Products and overwrite the old file.
• Be sure to revert all threadnav templates, including threadnav.css.
• Some pages will require simple template edits. See the ThreadNav setting sin the Admin CP for more information.

Bugs Fixed:

• Now compatible with vBSEO
• All text in phrases
• More tips on styling in threadnav.css
• Resolved major incompatibilities with some styles
• Miscellaneous aesthetic changes
• Resolved misalignment of borders of cell and drop box in some styles
• Improved closing of drop boxes when you mouse out
• Fixed more incompatibility issues with some some styles
• Fixed incompatibility issue with IE (GRRRRRRRRRR....)
• Overhauled system for opening and closing drop boxes

Style is based on borders, font-color and background-colors of postbits. For styles with darker colors a note at the top of threadnav.css gives helpful styling tips. If you need to add space above or below ThreadNav see top of threadnav.css. Don't use line breaks.

Installation is simple: upload the XML file to Products and you're ready to go -- no external files or edits.

Version 2.0 was developed in vB4.2.2 but should work in any vB4 version.

Oh by the way you should change your version been 1.0 ever since you made this mod should probably be at 2.0 version.

[nerbert]

What you could do for Seamus Red scroll buttons is change the background to this:

	background: 		rgb(80,16,21);  /*{vb:stylevar postbithead_background};*/

That's the average color of the red part. It just won't have the texture. If you don't like it you can change it back easily.

[venom2124]

disregard. I'm stupid and posting to the wrong mod.

[nerbert]

Surely with all the graphics on your forum someone could make some image buttons for your various styles. Just don't change the width!

I noticed another problem: in the Btech red and the others below it the last cell in Threadnav is only partly exposed. The problem is the JavaScript gets a measure of the width of the available space and calculates the cell width based on that. Normally in the course of loading the page it gets that dimension after the scroll bar on the left has popped up. On these styles there's a delay between the scroll bar popping up and the page narrowing to fit. Apparently it's getting the width at the wrong time and making the cells too wide. I'll work on an event listener or some other method to determine whether the width has narrowed.

Oh ok Thanks just let me know and i'll keep working with you on this Mod Thanks! :up:

Updated xml file to resolve more style incompatibility issues and problem with IE

Erica1977, this should make the cells come out correctly in all styles.

problem with this update see pic.

[nerbert]

Okay, the cells come out too narrow for you and too wide for me, but for the average viewer they should come out just right!

I looked at the source code for Btech and I see why there's a problem, and I have a vague intuitive phantom-like notion of how to solve it. I shall work on bringing my notion into concrete form
