Is there any way I can have a dialog box pop over on selection of particular picklist in the standard case object.

My use case is: If the user selects one of the picklist value from the dropdown in the case Object, user need to see the popup with the particular information on the dialog box popover.

I am trying to display the same thing as in the above screenshot as a popup in case object

Hi Mates,

I need a help on integrating salesforce to jira and viceversa without any plugin/addon/third party tools in developer edition

i was trying to push case from salesforce to jira as issue, and it is done using Callout working fine
But also need to push issue from jira to salesforce as case for this i created a webhook and created apex rest api class in salesforce and made that class as public from site, see below class

@RestResource(urlMapping='/JiraToSFRestTest/*')
global class JiraTOSFRestTestController {
  @HttpPost
    global static String doPost(String issueId,String issueKey, String projectId, String projectKey) {
        Case CaseObj = new Case();
        CaseObj.Status = 'Working';
        CaseObj.Origin = 'Web';
        CaseObj.Subject = issueId+'->'+issueKey;
        CaseObj.Description = projectId+'->'+projectKey;
        insert CaseObj;
        return CaseObj.Id;
    }
}

webhook url look like this
https://SaleforceSiteURL/services/apexrest/JiraToSFRestTest?issueId=${issue.id}&issueKey=${issue.key}&projectId=${project.id}&projectKey=${project.key}

I am executing this rest class from workbench then it is working fine but how to call this rest api class directly without login into salesforce from jira webhook
