Using a value from dropdown box

i am using a dropdown box to select a value
df=%sql -x select distinct rtrim(creator) as creator from sysibm.systables
drop=widgets.Dropdown(
options=df[‘CREATOR’],
description=‘Schema:’,
disabled=False,
)
display(drop)
drop.value
‘SYSCAT’
now I want to use this drop.value as an input for a new query
%sql select … from table … where name= $drop.value
this is handled as : %sql select … from table … where name=SYSCAT
but to be valid for the sql it should be … name=‘SYSCAT’
how can we force to keep these quotes around the variable ?
thanks for all update/help
best Regards, Guy
