    <p>I have two separate forms on the page and both of them have a group of checkboxes.</p> <pre><code>&lt;body&gt; &lt;form name="form1" id="form1" ...&gt; &lt;input type="checkbox" name="check1" value="Person" /&gt; &lt;input type="checkbox" name="check1" value="Dog" /&gt; &lt;input type="checkbox" name="check1" value="Cat" /&gt; &lt;/form&gt; &lt;form name="form2" id="form2" ...&gt; &lt;input type="checkbox" name="check1" value="Person" /&gt; &lt;input type="checkbox" name="check1" value="Dog" /&gt; &lt;input type="checkbox" name="check1" value="Cat" /&gt; &lt;/form&gt; &lt;/body&gt; </code></pre> <p>What I need here is, once the user check/unchecks any checkbox in form2, I want to do the same for corresponding checkbox in form1. If the user selects "dog" and "cat" in form2, check the same for form1 automatically. I have tried a couple of things but I can't figure out a way to set checked attribute based on the value field.</p> <p>Best I could to do is to have unique ids for all checkboxes and select/unselect based on ids. But I am trying to find out if there is a better selector way.</p> <p>Also, I will be glad if anyone can suggest me a better way to do what I am trying here. </p> <p>-- I haven't tried this yet, but this is what I was planning to do---</p> <pre><code> &lt;form name="form1" id="form1" ...&gt; &lt;input type="checkbox" name="check1[]" id="form1_Person" value="Person" /&gt; &lt;input type="checkbox" name="check1[]" id="form1_Dog" value="Dog" /&gt; &lt;input type="checkbox" name="check1[]" id="form1_Cat" value="Cat" /&gt; &lt;/form&gt; &lt;form name="form2" id="form2" ...&gt; &lt;input type="checkbox" name="check1[]" id="form2_Person" value="Person" /&gt; &lt;input type="checkbox" name="check1[]" id="form2_Person" value="Dog" /&gt; &lt;input type="checkbox" name="check1[]" id="form2_Person" value="Cat" /&gt; &lt;/form&gt; </code></pre> <p>once form2 checkbox is clicked, get the value, and look for checkbox in form1. If dog is selected, check $('#form1_'[dog]).checked('checked',checked)</p>

    1. COCan you show us what you've tried? I think you also want to use `name="check1[]"` or else only the last checked box will be submitted.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
