Alpha index hyperlink

hello
I'm using for a category a default type list (using a table to show the selected fields).
When The liste is complete : no problem the item title field appears and is an hyperlink.

If I ask the articles for a letter of alpha index, the item title field doesn't appear and I don get any feild to be an hyperlink

Hom can I correct this problem

thank you for help
Happy Christmas

Michel

it must be an issue with using
category menu item , with category parameters override,

- try disabling category menu parameter override in the menu and only using category configuration

The problem is elsewhere :
I have no menu category.
As I use an iframe (the articles are not in the same url than the one used to display them).

When I call firstly the list I finish the url with "&tmpl=component" to get only the list.
When I call for an index-alpha or for a subcategory there is no "&tmpl=component" and the CSS for hyperlink text color is white on a white background.

I'm not looking the CSS to be changed.

best regards
Michel
