RadMenu Double-Column Items Disappear on Resize

In the menu below, the Support Menu is double-column. When the vertical height of the screen is 

reduced (not necessarily even reduced so far as to prevent the whole menu showing), the items in the 

double-column menu disappear. They do not just disappear visually--nothing happens when you click where 

they should be, either. Even if you make the screen bigger again, they do not reappear.



We are using the Q3 .NET 4 DLLs. We are in IE8, but I verified this also occurs in a current Chrome.



Any fix?

OK, I'll make it single column for now, and test it again with the next release to see if you got the fix in. Would you add to the bug (or this might be a separate bug), the way I have formatted the double-column menu, the last menu item takes three lines. The second and third lines have an arrow to the right, as if they were the root of a submenu. The operation is correct, but the arrows are incorrect. Actually, this behavior appears with the single column menu as well (even though as a single column menu it's only two lines, and therefore only one arrow). So it's a separate bug.

Hi Velma,

In fact the appearance that you encounter is not a bug of the menu but rather expected "effect" when you alter the line height of the menu items without changing the sprite image. In case you need to get the desired appearance. however, you will also need to alter the sprite image that is applied as described in this help article.

All the best,

What you are saying is not making any sense to me so far. I looked at the article you sent me the link to, and it doesn't seem related to my circumstance.

To what do you refer when you say I've changed the height of the menu items? You're referring to the fix I applied to make a longer menu item wrap rather than being truncated? That fix was provided to me by you all. Really, I would not think that should require a fix, but should be the default behavior (that is, I would say the need to apply the CSS you provided represents another bug). But the behavior I am describing is clearly a bug. The menu is displaying a "sprite" that should indicate there is a submenu, when there is no submenu. The menu code is aware that it is only one menu item, as it behaves as if there is only one menu item. If the menu code is not aware that there are no subitems, then clearly it is broken--but it would appear to me it is aware there are no subitems and is nevertheless displaying the subitem indicator. I don't know what you could call that but a bug.

Maybe you could provide CSS that would hide those faulty subitem indicators?

Hello Velma,

My apologies for my previous response since I believe I could not quite understand the issue that you described. Please take a look at the attached image which I assume is the issue you refer to. If it is so, you get this appearance since you applied specific width to the GroupSettings of the RadMenuItem with Text="Support Tables". Therefore in order for the hover effect to render as expected it is necessary for the text not to fall on the second row. Thus, the appearance on the image is not a bug but rather implemented by design. In order to prevent the appearance from the image, however, you will need to either set different width to the GroupSettings or apply overflow: hidden to the dropdown of the menu (using the latest approach, however, will hide the text that goes outside of the dropdown).

Kind regards,
Kate

Hi Kate,

Thanks, but no, that's not quite it. You must have left off the white-space CSS tag, because the long menu item is not wrapping in your image.Here is my image (attached). My long item is wrapped. This is documented clearly and extensively:
http://www.telerik.com/help/aspnet-ajax/menu-appearance-item-css-class.html

But you see that on my menu, when the long wrapped menu item is hovered, a right-arrow appears, as if this was a menu with subitems. When I had the double-column menu, before we determined that that can't be used because of that serious bug, two right-arrows appeared.

These right arrows do not appear in the screenshots on the above-referenced page. (There is at least one screenshot that is specifically "hover".) And obviously they should not appear. So, (1) I am saying that they do appear is a bug and should be put in the queue to be fixed; and (2) how can I make them go away?--you would think I should be able to make them go away with CSS similar to the samples on that page.

Thanks.

Hello Velma,

My name is Ivan and I work as a front end here at Telerik. It's a multi part question with a multi part answer:

1) The Controls cover most cases out of box, but not all;

2) Those edge cases do require extra work and due the eye candy you have in the menu it might a little bit more work and probably sacrifice a bit of the candy but gain flexibility.

What I am saying is that we could help you by tweaking a skin of your choice that uses less candy for the appearance but be more flexible on the content. The candy I am taking about is the rounded corners, which will be achieved trough CSS and not images.

If that option is fine by you, we can proceed.

Thanks, Ivan,

Obviously I'm not getting it. I have to have a custom skin with custom graphics to get rid of the expand arrow where it doesn't belong? And you don't think the expand arrow appearing where there are no subitems is a bug? Beats me.

Maybe you could correct the documentation here:
http://www.telerik.com/help/aspnet-ajax/menu-appearance-item-css-class.html , to show the correct hover image with bogus expand arrow, and to document this behavior, and to document the custom skin--because it sure is a different scope of work than adding a style. ?

You're sure you can't give me a CSS that will make the arrows go? When I had one on a PanelBar I wanted to get rid of, one of your techs gave me this, which works great:
.RadPanelBar .NotCollapsible .rpExpandHandle {
visibility:hidden;
}

But if a custom skin is the only way, I guess ... It's not a good solution, not even with you offering to do the tweaking. But thank you.We are basing on WebBlue. I can send you the complete menu source, if that would help.

Should I open a support ticket? This seems to have rather gone on and on for the forums...

Hello, Velma.

Yes, a support request is the proffered way to communicate on this one. And wen you do open the support requests, please include a link to this forum thread, so we'll could have it as a reference.

We could go on with the forum thread, but then like, you noticed, you won't be able to attach any files other than images.
