When transcluded using AliasPlugin my pdf viewer which is displayed in a frame within a tiddler looses the z-index that I had applied using css. I have it defined in StyleSheet and applied it using <span class="pdfviewer"> and </span> nested just inside the <html></html> tags. When transcluded, all other css previously applied stays applied .but it displays in front of everything else. I even tried transcluding the applied css formatting and all the other formatting except z-index was applied. How do I display transcluded frame behind a top drop down menu? Anyone?
I finally ended up with both iframes and objects and to display my menus in front of them, I put an iframe shim in a tiddler and transclude that tiddler into my menu. It was a little trick with the search plugin im using but i used the div examples in pagetemplate for displaying tiddlers and it works there also. This transclusion thing is way cool. I'm now ready for tiddlywiki5 but I hope I can get it to run on ie7 somehow.
