Please describe the UI problem.

The plum-dispatch methods on this page do not render in an ideal way. This is mostly tracked at Qiskit/qiskit-addon-aqc-tensor#50, but there are point(s) in that issue that are specific to the rendering on the Quantum Platform (i.e., not yet present in the Sphinx output), hence this issue in addition to that one.
