title: jqgrid - checkbox for Group header to multiselect group items
body: <p>Currently I am using jqgrid to bind data. I have 2 questions:
  1) When Multiselect is true, we have a checkbox in the header row which selects all rows irrespective of grouping.</p>
  
  <p>What i am trying to achieve is to have a checkbox at the level of the group header. So each group will have a multiselect checkbox which when checked only checks all the rows in that particular group leaving the remaining groups as it is. </p>
  
  <p>If the checkbox option at the group header is not possible can we have the group header clickable so that we can check all the rows in that group?
  I found a similar question asked at <a href="http://www.sencha.com/forum/showthread.php?105831-Grid-GroupingView-with-Checkbox&amp;highlight=grid%20group%20header%20checkbox/" rel="nofollow" title="click here">click here</a> but they are not using jqgrid.</p>
  
  <p>2) My next question is can we embed .gif,.jpg images as part of the data in the columns in jqgrid?</p>
  
  <p>As I am a new user I'm sorry I wasnt able to add snapshots.</p>
  
  <p>Thanks</p>
