What does "Enable quick entry" do?

This works partially, dropdowns on forms do not seem to be supported for quick entry. Here is the first part of my snippet to rip family information from familsearch.org:

{import: /gf}
{note: insert=no; preview=no}
{formmenu: default=Full; Partner; Child; Child Partner; name=format; cols=25}
No. of Marriages {formtext: name=nm; default=2; cols=10}
No. of Kids 1st Marriage {formtext: name=k1; cols=10; default=9}
No. of Kids 2nd Marriage {formtext: name=k2; cols=10}
No. of Kids 3nd Marriage {formtext: name=k3; cols=10}
{gender={site: text; page=https://www.familysearch.org/; select=ifneeded; selector=[data-testid="conclusion-gender"]}}{names={site: text; select=ifneeded; selector=DIV[data-testid="section-card-family"] DIV.personBlockCss_pwehqel SPAN[data-testid="fullName"]; page=https://www.familysearch.org/; multiple=yes}}
{pidx=nm*2+1+k1+k2+k3}{w2idx=k1+4}{w3idx=k1+k2+4}
{endnote}
{note: preview=no}Debug:
parent at: {=pidx} / w2:{=w2idx}
{=names}{endnote}
{numbers=seq(1,k1)}{numbers2=seq(1,k2)}{numbers3=seq(1,k3)}
{=names[1]} {if: pidx<=count(names)}is a {if: gender="Male"}son of {else}daughter of {endif}{=names[pidx]}{else}parent's are unknown{endif}

I get:

Toggle field works, I have not yet tried other form field types.
