Datatranformation mlogit models

I want to run a multinomial model with season as a random factor. A lot of sources say mlogit models are the best option. However, I am very much confused by how I should format my data frame.

My goal is to make a model such as: Ecology = Group + Period + Method with hunting season as random factor.

For now, my data is in the wide format I guess. (Ecology is the response variable)

quota   pop_estimate    Ecology     Group   Period  method  season
440         2340        kitten   Family Pack   5      DD     11_12
440         2340      adult male    Solo       4      DD     11_12

Summarised my data looks like

 quota      pop_estimate          Ecology2           Group      Period  method      season   
 Min.   :314   Min.   :1865   1y female   :271   Family Pack: 263   1:348   DD:1624   11_12:336

 Median :440   Median :2490   2y female   :123                      3:373             13_14:422  
 Mean   :471   Mean   :2447   2y male     :256                      4:425             14_15:400  
 3rd Qu.:503   3rd Qu.:2700   adult female:273                      5:312             17_18:275  
 Max.   :589   Max.   :2740   adult male  :279                      6:239             20_21:148  
                              kitten      :401

How should I format my data in order to be able to use the mlogit command? I do not understand the explanation in the vignette (I am not experienced at all with this kind of models)...

Many thanks in advance!
