Ruby on Rails: Rendering element tags with html options if attribute is present -

-

I'm trying to present a label with an HTML attribute data-color , But only if an object attribute is available

This is what I have, but it is not presenting the label that I believe because it is saying that the attribute is not available, so the label Do not show attribute: 

  f.label: value, choice.label, category: 'fs-button', data_color: choice.color if Choice.attribute_pres Ent? : Color

If I present the object attribute, how do I set the html attribute data-color ? If the property does not exist then the data-color attribute should not be visible at all.

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
