I know that we cannot use business rule for mutli chocie column, so i created the js script for showing the field , only if users selects "Others" from the Multi choice column with the help of this blog

Hide and Show Subgrid on basis of selected option/value using JavaScript in MS Dynamics 365 CRM. – Microsoft Dynamics 365 CRM (wordpress.com)

I have multi choice column with name "intendedproductusers" and one of the choice is "Others" with value - '100000005'

If user selects "Others" then i want to show the column "intendedproductusersother" or else hide this column

function Showhidecoulmn(executionContext) {

var formContext = executionContext.getFormContext();

var raiseRequest = formContext.getAttribute("intendedproductusers").getValue();

if(raiseRequest == 100000005)

{

formContext.getControl('intendedproductusersother').setVisible(true);

}

else

{

formContext.getControl('intendedproductusersother').setVisible(false);

}

But when i used the above code and followed the same steps as in blog, but it was working, let me know if I'm missing something here?

}

Hi psk_12,

For multi chocie column, you can select multi choices at the same time.

As long as the selected option contains "Others", the condition is met, you can refer following code(just change column name):

function Showhidecoulmn(executionContext) { var formContext = executionContext.getFormContext(); var raiseRequest = formContext.getAttribute("new_intendedproductusers"); //Returns Array of Selected OptionSet Values var selectedOptions = raiseRequest.getSelectedOption(); if (selectedOptions.filter(i => i.value === 100000005).length > 0) { formContext.getControl('new_intendedproductusersother').setVisible(true); } else { formContext.getControl('new_intendedproductusersother').setVisible(false); } }

Test:

(1)Fields:

(2)Add js resource to 'intendedproductusers' field onChange event

Result:

Hello

i was testing the form and everything is working fine used the same code you had given, but just had one issue when I select some option in multi choice column and then I remove it , I'm getting the below error, if I select again some options then it will work properly.

when I open the new form then i will not receive any error, only when i select option and remove all options then i get this error, basically when i select something and then i remove it only if field is blank i get error, may something to do with this line not sure - if (selectedOptions.filter(i => i.value === 100000005).length > 0)
