title: PyQt5 QComboBox list items changing postion
body: <p>I am facing some issue with the display style of Qcombobox items. Currently am hardcoding the data to be shown in the combobox. </p>
  
  <p>here is the code :</p>
  
  <pre><code>self.Dummy = QComboBox(self)
  self.Dummy.setGeometry(200,600, 350, 50)
  
  self.Dummy.setStyleSheet("QComboBox {background-color: white;border-style: outset;" border-width: 2px;border-radius: 5px;border-color: #448aff; font:  12px; min-width: 10em; padding: 3px;}")
  
  self.Dummy.addItems(["-Select-", "2", "3","4","5","6","7","8","9","0","11",])
  </code></pre>
  
  <p>The issue is that the dropdown "list" postion keeps changing after each selection. Here is the image of the issue am facing. </p>
  
  <p>Below is my combobox </p>
  
  <p><a href="https://i.stack.imgur.com/7LNJx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7LNJx.png" alt="enter image description here"></a></p>
  
  <p>The list contains items <strong>&lt;-Select->,2,3,4,5,6,7,8,9,0,11</strong> , where &lt;-Select-> will be the first element shown. </p>
  
  <p>Now when I click the box, the box list "down" the elements and suppose I selected '2'. Then, if I try to select another item, the list will be dropped in a "downwards" direction. see below</p>

  <p>Now, say if  selected the last element from the items, '11'. Now if I try to select a new item by clicking on the box, the list will be popped "up" instead of down. see below</p>

  <p>What should be done to fix it ? I don't think its an issue with stylesheet, without it also, this issue is happening. The reason I need this to be fixed is that when the list is popping up, its covering the label above it</p>
