Using the following code:

<a onclick="NewItem2(event, this.href); return false;" href="your">https://mywebsite/_layouts/listform.aspx?PageType=8&amp;ListId={3EDFF639-D37D-49F9-8140-1B46DBC2FC00}&amp;RootFolder=">your link name</a>

It opens into an infopath form on a sharepoint list. The dialog opens, but it is cropped and cannot scroll. I have searched for hours to get an answer and am getting frustrated. Help!

Hi Ky- this sounds like you have a fixed width/height whether you set it or not. I'd check your CSS. Did you see this link?

Did not see that. Assuming this means the person has access to Sharepoint Designer? Any chance I can apply the CSS to the popup in a content editor web part?

You can add CSS to a page using a CEWP. See the first link for the CSS and the second for adding it via the web part:

Tried one of the solutions and my code looks like this. Am I doing something wrong?
