Convert list containing lists of different length to a data frame in R

Question

I have a list, which contains lists of different length. Each of these sub-lists contains a vector of the same length.

My goal is to get a dataframe, where each of these vectors is a row. Every solution I came across was not usable because the sub-lists don't have the same length. One example of my list below

[[1]]

[1] "CGATCTGCTTCTATT" "1" "GA/TC" "DpnI"           

[[1]][[2]]
[1] "CGATCTGCTTCTATT" "1" "/GATC" "DpnII Sau3AI MboI"

[[2]]

[1] "AGATCTGCTTCTATT" "1" "A/GATCT" "BglII"

[1] "AGATCTGCTTCTATT" "1" "GA/TC" "DpnI"           

[[2]][[3]]
[1] "AGATCTGCTTCTATT" "1" "/GATC" "DpnII Sau3AI MboI"

[1] "CGATCCGCTTCTATT" "1" "GA/TC" "DpnI"

[1] "CGATCCGCTTCTATT" "1" "/GATC" "DpnII Sau3AI MboI"

[1] "AGATCCGCTTCTATT" "1" "GA/TC" "DpnI"           

[[4]][[2]]
[1] "AGATCCGCTTCTATT" "1" "/GATC" "DpnII Sau3AI MboI"

[[5]]

[1] "CGTTCAGCTTCTATT" "1" "AG/CT" "AluI"           

[[6]]
[[6]][[1]]
[1] "CGCTCAGCTTCTATT" "1" "AG/CT" "AluI"

Each of these "CGCTCAGCTTCTATT" "1" "AG/CT" "AluI" should be a row in the dataframe
