Hi, I'm trying to make Codoforum ready for Persian Language , so I need to change page direction to RTL because Persian language is a RTL language. when I use RTL attribute as global, in view of creation of new topic UI (Create Topic) a Strange orphaned input element will appear. you can see it in comparison:

1 . When using no RTL :

2 . When using RTL :

I have marked it in the picture, so for more details, I made another screenshot from element details:

Browser: Opera beta 27.0

I can hide it using CSS, But I want to know what is it ? is it safe to hide it using

someStyle{display:none}

or what ?

Hi,

We never tested RTL because we are not familiar with the language.

The strange input that you are seeing is a honeypot method that is used to prevent spamming.
It was hidden using css but became visible due to rtl.

You can hide it by making the following change:

Open sites/default/themes/default/less/general.less

And replace

.end-of-line {
    position: absolute;
    margin-left: -99999px;
}

with

.end-of-line {
  border: 0;
  clip: rect(0 0 0 0); 
  height: 1px; 
  margin: -1px;
  overflow: hidden; 
  padding: 0; 
  position: absolute;
  width: 1px;
}

Can you have some more tests and see if you can find any other problems ?

I'm using a custom RTL theme , a copy of default blue theme and added your css to the custom.less file:

.end-of-line {
  border: 0;
  clip: rect(0 0 0 0); 
  height: 1px; 
  margin: -1px;
  overflow: hidden; 
  padding: 0; 
  position: absolute;
  width: 1px;
}

and wow ! no more orphaned input, so as I understood, it should not be {display:none} . it is the result:

thank you
