Parameter description:
Edithidden: Valid only in form editing mode, set to True to allow hidden fields to be modified as well.

Integer: whether integers
MinValue: Maximum Value
MaxValue: Minimum value

Custom: Set to True, it is validated by a custom JS function. The function is defined in Custom_func.
Custom_func: The value passed to the function is one that requires validation of value and the other is the name attribute value defined in Colmodel. The function must return an array, one that is the result of the validation, true or false, and the other is the prompt string for the validation error. such as [False, "Please enter valid value"].
Examples of custom validation:
    <script>
        function Mypricecheck (value, colname) {
         if (value < 0 && value >20)  
            return [False, "Please enter value between 0 and 20"];
        else 
            return [True, ' "];
       }

         jQuery ("#grid_id"). Jqgrid ({
        ...
           Colmodel: [ 
                
               {name: ' Price ', ..., editrules:{custom:true, Custom_func:mypricecheck ...}, Editable:true},
              ...
          ]
        ...
       });
    </script>   

formoptions(only valid in form editing mode), his main function is to reorder the editing elements in the form, and to add some information (for example, some hints or a red *) before editing the element or after editing the element. Indicates that it must be filled out, etc.).
The optional properties are as follows:
Elmprefix: String value, if set, some content will appear after the edit box (possibly HTML content)
Elmsuffix: String value, if set, some content will appear before the edit box (possibly HTML content)
Label: string value, if set, this value will replace the value in Colnames appears as the label of the edit box
Rowpos: A numeric value that determines the position of the element line in the form (relative to the text label again with the Text-label)
Colpos: A numeric value that determines where the element is listed in the form (relative to the label again with the label)
Two edit boxes can have the same Rowpos value, but the Colpos value is different, which puts the two edit boxes in the same row of the form.
Special NOTE: If you set the values for Rowpos and Colpos, it is highly recommended that you set these values for all other editing elements.
