Better UI experience for Settings and Rules section in the metadata schema

[#1]

Request for Feature Enhancement (RFE) Summary:	Better UI experience for Settings and Rules section in the metadata schema
Use-case:	To be able to create metadata schemas easier and faster
Current/Experienced Behavior:	1. When scrolling to the bottom of the metadata schema form (especially when it has numerous fields), the "Settings" and "Rules" section are no longer visible. 2. When selecting fields already in the metadata schema, "Build Form" option is also visible. This can lead confusion to the users as users might think that "Build Form" is a setting of the selected field.
Improved/Expected Behavior:	1. When scrolling to the bottom of the metadata schema form (especially when it has a lot of fields), the "Settings" and "Rules" sections should follow with the scrolling or "stick" to the page. The "Settings" and "Rules" sections should always be visible so that it would be easy to change the settings when selecting the fields.  2. When selecting fields already in the metadata schema, "Build Form" option should not be visible so that "Settings" and "Rules" section are the only ones displayed. Another option is that the "Build Form" can also be placed in the left side of the page so that it would be separate from the field settings.
