Equations can be aligned to the Baseline, Bottom Level or Top Level.
This setting can be controlled by a superset setting or it can be modified for each equation. It is recommended that you choose the alignment that will be most frequently used and set that within the superset.
To change the superset setting:
Modify the Multilevel Base Alignment option
To modify one equation’s alignment:
Modify the Multilevel Base Alignment option
Sample import text:
Mainline Base Align: [&x|=|*frac*{1}{2y}&] Bottom Level Base Align: [&~BB~x|=|*frac*{1}{2y}&] Top Level Base Align: [&~TB~x|=|*frac*{1}{2y}&]
Importing the text into an InDesign document should result as follows if your superset base alignment is set to Mainline Base Align:
