I am using Selenium 2 Java API with FirefoxDriver. When I fill a form, checkboxes are added to the page depending the forms inputs.
I'd like to simulate a click on those checkboxes using Selenium. The element are visible and usable in a regular browser but, selenium asserts that the elements are not visible.
"Element is not currently visible and so may not be interacted with" Can I force selenium to ignore the non-visible state of the elements? How can I force Selenium to interact with the non-visible element?

How do you click on an element which is hidden using Selenium WebDriver? We can click on an element which is hidden with Selenium webdriver. The hidden elements are the ones which are present in the DOM but not visible on the page. Mostly the hidden elements are defined by the CSS property style="display:none;".
Selenium by default cannot handle hidden elements and throws ElementNotVisibleException while working with them. Javascript Executor is used to handle hidden elements on the page. Selenium runs the Javascript commands with the executeScript method. The commands to be run are passed as arguments to the method.
First Solution: Try to write unique XPATH that matches with a single element only. Second Solution: Use Explicit wait feature of Selenium and wait till the element is not visible. Once it is visible then you can perform your operations.
We can wait until an element is present in Selenium webdriver. This can be done with the help of synchronization concept. We have an explicit wait condition where we can pause or wait for an element before proceeding to the next step. The explicit wait waits for a specific amount of time before throwing an exception.
Selenium determines an element is visible or not by the following criteria (use a DOM inspector to determine what css applies to your element, make sure you look at computed style):
Your element is matching one of those criteria. If you do not have the ability to change the styling of the element, here is how you can forcefully do it with javascript (going to assume WebDriver since you said Selenium2 API):
((JavascriptExecutor)driver).executeScript("arguments[0].checked = true;", inputElement); But that won't fire a javascript event, if you depend on the change event for that input you'll have to fire it too (many ways to do that, easiest to use whatever javascript library is loaded on that page).
