lengthen page to show whole google form?

Please post a link to the page where the problem can be seen.

That height appears to be set as part of the iframe you’re embedding:

<iframe width="760" height="500" frameborder="0" marginwidth="0" marginheight="0" src="https://docs.google.com/forms/d/1UmNhCE-UsBe_7x2zCx1HtKhD0DaFf3ZqRSQk5RF2SDU/viewform?embedded=true">

Is that from a plugin?

In case you don’t have control of the height otherwise, try adding this to the end of your theme’s style.css:

#post-699 > .entry > p > iframe {
    height: 1783px !important;
}

You should create a Child theme to make your changes. If you do not, all of your changes will be lost if you update your theme.

pdean — can you send me the code to embed the form into the site? I’m using version 3.6.1 and can’t figure it out
