html - CSS Dropdown menu isn't shown even though absolutely positioned because of overflow: hidden -

-

I am trying to show a dropdown menu on the hover, but I have to apply the overflow too: hidden the original element has gone. As a result, my dropdown is complete, though it is fully deployed, it is not visible (due to overflow: hidden).

I have reproduced the problem there: (you can edit the code to edit the full source code / code)

(small sample) 

  # block-paddle-menu-display-first-level. Menuu_wrapper.level-2 {status: absolute; Visibility: hidden; } # Block-pedal-menu-display-first-level Hass-kids: Hover menu. Level -2 {visibility: visible; Padding: 15px 0; Background: black; Width: 300px;   
 Under the list item "hover here -...", there is a nested ul that should be shown on the hover.  
  Needs   
     
  •  Overflow: The arrow is required to slip the effect to work / hide on the parent (this test does not work perfectly on the case, but now it is  
  •  We need the menu background color to expand on the whole page   
     Related questions, lake Not 100% equal:   
     
     
      block-paddle-menu-display-first-level { Overflow: view;}   
     and add  display: inline-block;  Work your way from that point.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
