Selenium webcrawling combo box

Question

I am trying to click a java script combo box in python, however If i do it normally, it gives me an error saying that the combo box is hidden, I programitcally wait for the combo box to appear but it does not appear. This option in combo box is a sub menu, however, if i select just an option from real menu it works but not with sub menu options. This is the website, https://mbsdisclosure.fanniemae.com/PoolTalk2/index.html, > Advanced Search > #then the combo box I am looking for the sub menu option for Preliminary Mega > Preliminary Mega: Fannie Mae/Ginnie Mae backed Adjustable Rate . Thanks!

Selenium won't be able to click as element you want to select is considered to be invisible(inactive). So the only way(imho) to use js to resolve this issue. That worked for me in java:

 @Test
    public void neeededDropdownSelect() throws InterruptedException {
        driver.get("https://mbsdisclosure.fanniemae.com/PoolTalk2/index.html");
          jsClickOnElement("li#tab_1>a>span");
        WebElement dropdownMenu = fluentWait(By.cssSelector("span#asSelectedSecType"));
        dropdownMenu.click();


        jsClickOnElement("div[class=\"fg-menu-container ui-widget ui-widget-content ui-corner-all fg-menu-flyout\"] ul[class=\"fg-menu ui-corner-all\"]>li>a[id=\"MEGA_INTERIM\"]");
        jsClickOnElement("div[class=\"fg-menu-container ui-widget ui-widget-content ui-corner-all fg-menu-flyout\"] ul[class=\"fg-menu ui-corner-all\"]>li>ul.ui-corner-all a[id=\"MEGA_INTERIM_ARM\"]");

    }

  public WebElement fluentWait(final By locator){
        Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
                .withTimeout(30, TimeUnit.SECONDS)
                .pollingEvery(5, TimeUnit.SECONDS)
                .ignoring(NoSuchElementException.class);

        WebElement foo = wait.until(
                new Function<WebDriver, WebElement>() {
                    public WebElement apply(WebDriver driver) {
                        return driver.findElement(locator);
                    }
                }
        );
        return  foo;              }     ;

    public void jsClickOnElement(String cssSel){
        JavascriptExecutor js = (JavascriptExecutor) driver;
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("var x = $(\'"+cssSel+"\');");
        stringBuilder.append("x.click();");
        js.executeScript(stringBuilder.toString());

    }

Hope this helps you)
