How to make Sub Category mandatory

[Alon Grod]

Hi,

I have the fields Category and Sub Category on the incident table. Sub Category values are dependent on Category. For some values on category there are sub categories and some of the values of categories don't have values in sub category. How can I make Sub Category field mandatory only if he has values according to the Category that was chosen ?

@Sai Shravan @Prince Arora  this is the code Im using. The first time that Im choosing a category, Im getting Alert count of 1, even though Im choosing a category that has 18 choices. Then the 2nd time that Im chossing a category im getting alert count of 1 + the choices that I was supposed to get in the first time so total 19.
for some reason its adding the choices and it start from one in the first time that Im choosing a category.

Hi @Alon Grod,

The None option is also counted in the options and you can try by changing the if condition to

if (options > 1)

@Alon Grod ,

Please change your client script as onChange of "subcategory" and mention the code snippet as mention in below code as it is taking 'none' as a option so you will get the value as n+1 always.

As per the previous code there is a lag between the code because once you selected the option it will change the options and return the output of the subcategories of previous selected "category"

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
var subcat = g_form.getControl('subcategory');
var options = subcat.options.length;
alert(options);
return;
}

//Type appropriate comment here, and begin script below
else {
var subcat = g_form.getControl('subcategory');
var options = subcat.options.length;
alert(options);

if (options > 0) {
g_form.setMandatory('subcategory', true);
}
}

@Prince Arora  it is still showing me the previous choices and not the actual choices of the chosen category and sub category

Hi @Alon Grod ,

I hope the alert is showing the previous sub - category count, but the value are as per the selected category and the sub-category becoming mandatory. 

you can try by changing the if condition to

if (options > 1)
