Can I use xpub external key in electrum?

[ChzenChzen]

I want to import xpub from joinmarket into electrum, for generating addresses for inputs. Is it possible?

Yes but there are some details. First, joinmarket uses 5 bip32 accounts by default, electrum by default only uses 1, but i believe you can specify the wallet path (e.g. m/84'/1'/1' which refers to account 1 (the second, starts at 0) in a BIP84 wallet) as part of wallet creation in Electrum (I know it used to be the case, so it probably still is the case). Second of course we use BIP84 which is the commonly used standard for bech32 single signature (p2wpkh) wallets, Electrum may or may not recognize that, several other wallets I know, do, please consult Electrum about that, and if it doesn't directly recognize it, see above. Third, the xpub for your 0th mixdepth (=account 0) is shown both on the command line and in JoinmarketQt when you display the wallet, you can take it from there. If you want to interact with other mixdepths (accounts 1..4) you will have to note the above point about entering custom bip32 wallet paths.

I think Electrum will want zpub for bech32 addresses, see #558. You can use something like https://github.com/jlopp/xpub-converter to convert from xpub to zpub.
