Hello. Thank you for contacting the Toolset support.
Well - you can build calendar using Toolset plugins but it may require custom programming at certain places but the wise decision could be to use the already existing Calendar plugins which will save lot of time and efforts.
well i was planing to use toolset on a new site with DWT listing theme. and that calender plugins cant be connected with that.
will toolset be able to play the roll of the bridge to fetch event and place them on the above mentioned plugins?
Well - I see most users use Events Calendar plugin but I advise you to check the feasibility of your requirements and try to play with it.
We offer "Framework Installer" plugin that you can use to install the reference sites we offer that will help you to install any reference sites on your local/staging server and once you install it - you can try to install your desired calendar plugin and check the feasibility and use the Calendar plugin that suits best as per your requirements.
