Hi Stephen
i am able to change the place holder value using rule. Only problem it is not dynamic. If i write rule on update the field then it will change the value of the text box i don't want to do that. i just want to change the place holder of the text depend on the value i have selected in drop down list. Like in drop down list i have some languages. The default one is English so in place holder it shows English. Now i change the value of drop down list to french then i want in place holder text as French.
